Selection of Authentication Function According to Environment of User Device

3. The method of claim 1, wherein the sensor data is associated with a low-power sensor of the user device that facilitates an always-on context detection capability when a user interface of the user device is in a locked state.

5. The method of claim 1, wherein the authentication component is a separate component of the user device from the sensor.

8. The method of claim 1, wherein the environmental context is determined further based at least in part on a machine learning model that is trained based at least in part on historical sensor data associated with corresponding historical usage of one or more of the plurality of authentication functions.

13. The user of claim 11, wherein the sensor data is associated with a low-power sensor of the user device that facilitates an always-on context detection capability when a user interface of the user device is in a locked state.

15. The user device of claim 11, wherein the environmental context is determined further based at least in part on a machine learning model that is trained based at least in part on historical sensor data associated with corresponding historical usage of one or more of the plurality of authentication functions.

23. The non-transitory computer-readable medium of claim 22, wherein the sensor data is associated with a low-power sensor of the user device that facilitates an always-on context detection capability when a user interface of the user device is in a locked state.

27. The apparatus of claim 26, wherein the sensor data is associated with a low-power sensor of the user device that facilitates an always-on context detection capability when a user interface of the user device is in a locked state.

29. The apparatus of claim 26, wherein the environmental context is determined further based at least in part on a machine learning model that is trained based at least in part on historical sensor data associated with corresponding historical usage of one or more of the plurality of authentication functions.
